1. Place butter in a 2-cup glass measure or microwave-safe dish. Microwave on 100% power 30 to 45 seconds to melt butter.

2. Stir sugar and egg into butter. Microwave on 50% power until sugar dissolves and sauce thickens (2 to 3 minutes), stirring once during cooking. Cool slightly, then stir in bourbon.
